EBEN R. PACKER, OF WILMETTE, ILLINOIS, ASSIGNOR TO Q 8a C COMPANY, 0FNEW YORK, N. Y., A CORPORATION OF MAINE.

PORTABLE DERAIL.

Application filed September 18, 1915.

T 0 all whom t may concern Be it known that I, EBEN R. PACKER, a citizenof the United States, residing at Wilmette, county of Cook, State ofIllinois, have invented a certain new and useful Improvement in PortableDerails, and declare the following to be a full, clear, and exactdescription of the same, such as will enable others skilled in the artto which it pertains to make and use the same, reference being had tothe accompanying drawings, which form a part of this specification.

My invention has for its object to produce a portable derailing devicewhich is applicable to rails of various sizes, may be placed on orremoved from a rail quickly and conveniently and, when on a rail,automatically lock itself against creeping in advance of a wheel to bederailed.

The various features of novelty whereby my invention is characterizedwill hereinafter be pointed out with particularity in the claims; but,for a full understanding of my invention and of its object andadvantages, reference may be had to the following detailed descriptiontaken in connection with the accompanying drawing, wherein:

Figure 1 is a side elevation of a fragment of a railway rail havingthereon a derailing device arranged in accordance with my invention;Fig. 2 is a top plan view of the parts shown in Fig. 1; and Fig. 3 is aview looking toward the left from the right hand end of Figs. 1 and 2,the rail being shown in section.

Referring to the drawing, 1 represents a railway rail and 2 a derailingblock adapted to derail a wheel passing along the same in one directionthat is from the right toward the left in Figs. 1 and 2, and permit awheel going in the opposite direction to pass freely over the same. Onone of the long sides of the block is a long depending fiange, 3, havingits lower end bent inwardly as indicated at 1- to underlie thecorresponding side of the head of a rail to which the block is applied.The flange is made deep enough so as to permit the insertion of any ofthe standard rail heads between the bottom of the block and the top ofthe inwardly projecting portion, 4 of the flange. On the under side ofthe block opposite to the flange 3 and having its mouth directed towardthe same is a jaw, 5, in which lies a rotatable locking dog, 6, held inplace by a vertical Specification of Letters Patent.

pin or shaft, 7. The inner end of the locking dog is gradually curved,as indicated at 8, on a radius which increases gradually from the frontend, that is the end toward the derailing end of the block toward therear; the parts being so constructed and arranged that some portion ofthe cam surface, 8, will engage with the web of any rail on which theblock is adapted to be placed and cause the rail to be clamped betweenthe dog and the flange, 3, of the block.

It will be seen that when a wheel engages with the derailing end of theblock, that is the right hand end in Figs. 1 and 2, any movement of theblock in advance of the wheel would result in a corresponding movementof the pivotal point of the dog while the cam face of the latterremained fulcrumed on the web of the rail. The result would be aswinging of the locking dog and an increase in distance from the web ofthe rail to the pivotal point of the dog or, in other words, atightening of the clamping action. A projecting portion of the dog atone side of the jaw, may be provided with a series of holes, 80, throughwhich the shackle of a lock, 9, may be passed so as to prevent theunauthorized removal of the block from the rail. If desired, the blockmay be provided with an upwardly projecting lug, 10, which may easily bestruck with a hammer for the purpose of releasing the locking dog afterit is wedged tightly in place through use.

While I have illustrated andv described with particularity only a singlepreferred form of my invention, I do not desire to be limited to theeXact structural details thus illustrated and described; but intend tocover all forms and arrangements which come within the terms employed inthe definitions of my invention constituting the appended claims.

I claim:

1. In combination, a derailing block having on one side a dependingflange and on the other side a jaw having, its open side directed towardsaid flange, and a camshaped locking dog mounted in said jaw to swingabout a vertical axis, a portion of said dog projecting outwardly beyondone side of said jaw and being provided with perorltions for receivingthe shackle of a pad- 2. In combination, a derailing block havflange,anda cani-g `perfomtions for receiving the shackle ol n pad-look, thedog having at an outer point thereon an upwardly projecting lug. 10

In testimony whereof,v I sign this speciication.
